User onboarding metrics are quantifiable measurements used to assess the success of a product's user onboarding process. These metrics can include completion rate, time to value, activation rate, free-to-paid conversion rate, retention rate, user satisfaction, ticket volume, and churn rate. By tracking these metrics, companies can gain insights into their users' experiences and make improvements to their onboarding processes. Effective measurement of user onboarding metrics requires a granular breakdown of the user journey and utilization of analytics tools, data warehouses, and customer feedback platforms.
